Hello, CN4 offer you a way to connect an additional power source (through SOURCE and GND pins). Thus the power comes from outside. There's a 3.3V to supply any additional electronics. There're other two pins, named I2C_xx, that are connected to MCU...
Hi H.Aoki, you can use CN4 to retrieve power from an external power source (you may provide). On FW, inside usbpd_dpm_user.c file you may see USBPD_DPM_SetupNewPower calling USBPD_PWR_IF_SetProfile handling different profile requests. In case of FI...
Hello Again,let me understand better so.If you are a charger, so a source, you should be sure about your power; so I assume that there's no issue on source side.Now you're reporting a "device" to be charged thus the application use case becomes uncle...
Hello FC1,I totally agree with Daniele for item 2.Why you need PD communication if you're providing only 5V? Are there any other reasons?As regards application side, according to me, you have 2 option: PD Controller like STUSB4761 that can manage all...
Hi DRH, thanks a lot for your question. Let me note two things by Type-C specs: - vVCONNValid (The voltage range over which VCONN is considered valid on Source side) is between 3V and 5.5V - Power for Sources in USB Suspend or without TX/RX Signals m...
